Granted, but your Muse becomes physically strong. Having a really buff Muse doesn't do you a bit of good, and in fact, it actually leaves you with even less inspiration since your Muse is always admiring herself in the mirror, working on her body, keeping her muscles toned, etc.
Oh, and she whoops your ass on a daily basis.
I wish I really could go back to the future.
